All the heada in F, were smooth but it is possible 

 that a microscopic examination would have shown velveting 

 of the glumes. Biff en reports velveting to be dominant. 

 The studies in ?£ iniioate that this is the case. 



In P-, tlie tightness with which the glumes adhered to 

 the kernels was intermediate in character. A detailed study 

 of this was not made on Fg plants. A very profitable study 

 could be made on this character as the shattering of wheat 

 is a serious problem In some districts where the grain is 

 permitted to become very ripe before harvesting, A wheat 

 with a glume that adhered more closely would be much more 

 desirable than the ones now grown if this character could 

 be combined with the desirable characters already possessed 

 by the present wheats. 



The following photographs show ch&racteristic heads 

 of the wheats and emmer used. The heads of the parent 

 stocks used for the crosses are shown together with a head of 

 the F]_ plants. Some of the characters described above are 

 apparent in the photographs.
